To all whom t may coneem:

Be it known that I, Ronlrr TEMPLE, a subject of the Kino' of GreatBritain, residin f at Bromley, in the county or' Kent, Englan haveinvented certain new and useful Improvements in Explosivel -ActuatedPenctrating Means, of which t e vfollowing 1s a specification.

This invention relates to improvements in explosively actuatedpenetrating means and has for its object to provide a new and improveddevice comprising a penetratin member, an explosive actuating charge, anmeans to detonate the explosive charge, in combination with otherstructural features hereinafter described.

My invention is especially adapted for use in submarine work, forexample, where it is desirable to aix repair plates or the like to thehull of a vessel in a minimum of time and with a minimum of eii'ort,"orwhere it is desirable to attach projecting means to the hull of thevessel to which or'by which may be secured lines. There vare'nnrnerousother uses to which my invention can' be put.

The embodiment of my invention illustrated in the drawings comprisesprincipally a holder, a barrel and a projectile aflixing member,consisting of a member adapted to bc projected by an'explosive chargeinto thc metal sheet or body to which it is to be affixed.

Another object of my invention consists in providing a device of thecharacter described in which one holder may be utilized with any numberof barrels and projectiles so that the user may attach a new barrel withprojectile contained therein with a simple operation.

Another object consists in the provision of mechanism of the characterdescribed, in which the user will be' protected from concussion underwater.-

These and other objects will'bc more fully described and set forth inthe following specification and shown in the accompanying drawings, inwhich- Figure l is a vertical cross section through a structurelembodyingmy invention, showing the same located against the side of avessel preliminary to attachment of the missile.

Fig. 2 is a detail showing'the penetration of the projectile afteractuation.

Fig. 3 is a transverse horizontal section along the line 3-3 of Fig.1.",

' mit iow of the line of Fig. 1.

Like characters refer to like elements throughout the drawings, in whicha desi `natos what I term the barrel. Located in t e barrel 1s an alxmgprojectile member which comprises a fastening means arranged topenetrate'the body to which it is to be attached. This projectilecomprises the element b shown as tapered and having spiral grooves tofacllitate penetration, and to perenetrated metal into the groove tosecure t e rojectile in its aiiixed position, this projecti e beingpreferably constructed of hlghly tempered steel or the like. Locatedabove/the projectile b is the cup b1 closely fitting the bore of thebarrel a, provided with a cup shaped depression forming relativelythin-walls b2. Extending through the bottom of the cup b1 and engagingthe upper portlon'A of the projectile b is 4the threaded screw c whichnormally secures the -projectile b to the cup b as shown'in Fig. l.

An explosive charge of predetermined quan? tity and explosive forceindicated by the letter d 1s carried in the cup b1. Located above thccup secure to the cup b1 and projectile b by Fi 4 is a similar sectiontaken along the b1 Visthe detonator block e normally means of the screwc. `Located. between the detonator block e and the cup b1 above thetough material, such as copper or the like. The barrel ais slightlyenlarged to accommodate the block e, forming a shoulder e2 on which thedisk g rests as shown in Fig. 1. This detonator block e is provided witha cup or depression inwhich 1s mounted a detonator f, a firing hole e1leading from the detonator chamber to the explosive charge d.

Located above lthe block e and detonator f is a disk k of copper or thelike secured in place by the threaded plug i, which engages athreadedportion of the bore of the barrel a. This lug i is centrallyapertured at 'i2 and provlded with a cross slot 2'. for engage.centrally pertured- .0r bored t0 fewer-the,

end of the holder and provided with a longi- `tu inal slot k2 on thelnterior iu which may sli le the lug Z on the sleeve Z. This slot k2terminates above the bottom of the holder 1 5 und prevents withdrawal ofthe barrel after onvageineut of sleeve Z with plug The ho der Z: isfurther provided with an enlarged portion 708 in which is pivotallymounted a detent m mouutedupon the pin IO m1 and havmg a hooked end m2lnormally engaging the top of the sleeve Z as shown in Fig. l, beingmaintained in such position by the spring m3 and removable from suchposition by the handle portion m* which projects outside of the holderk. Screwed into the top of the latter is the handle 7:'1

which also serves to maintain the firing rodjl in the holder inthe seatprovided b 'the shoulder i as shown' in Fig. 1. This ring rod isprovided' with a firing pin portion y' of considerabl smaller diameterthanythe firing rod andy small opening z" in the bottom of plug' z. A

coiled spring a is located in the holder-'7c f '25 and extends betweenthe top of sleeve Z and.

' the bottom of the firing rod jl as shown in Fig. 1. An aperture 7c isprovided'in the upper portion of the barrel av to" permit evress ofwater from the holder k in actuation of the device.'

The'exte'rior of the barrel a, at the muzzle is externally threaded andengaged by the nut q which is internally apertured to '.iiorin aprolongation of the bore ot the barrel a of less diameter for a purposeto be hereinafter described.v An4 internal shoulder q2 is provided inthenut g in which is seated a isk g1 of copper, or the like nminally clos--ing the bottom of the bore oi thc barrel 40 against ingress of water,the upper portion of the bore being sealed by the disk L. Lo-

cated between the disk 91 and the muzzle of the barrel a is the block o'centrally apertured to form a reduced continuation'of the bore of thebarrel and' secured in place by the nut g. v The block o is provided'with a seat 01 and also serves to maintain a disk y) heldy against themuzzle of the barrel a., this disk p being centrally aperti-nedl at p1to permit relatively easy penetration thereof by the projectile b.

. In the use of my device, for example,

where it is desired t'o secure. a repair plate 'r to a side r1 of a shipor some other submerged body, the holder and muzzle be- 'ing inassembled relation, as shown in Fig. 1, are placed by the user with theend 'of the nut g against plate r which may have a predrilled holetherethrough after which,

o'while grasping the handle k1 the user may disengage the detent 'm fromengagement with the top of the sleeve Z, after which the holder c may beforced downwardly' upon the barrel a against the action of th'e s )ringu'ntil'theiring' pin j strikes the disk ,de-

capable of penetrating the- -pressure off the explosive charge untilsame has built up'tofa desired point, when the screw c will fracture atthe notched portionl c1 and the rojectle b with the cup b* will beprojected) downwardly 'in the bore of thel barrel a as viewed i nFig. 1. The sides of the cup b1 being comparatively thin. -will bemaintained in close contact with the bore so owing to the expansionI ofthe. gases, and as l have constructed the cup b1 and the p1o. 'ectile Z)of relatively small mass, they will e rapidly driven thro-ugh the boreof the barrel a, the projectile b passing' through 85 disks p and (j andthrough the plate fr and side of the vessel r1.' As the projectile andcup arel a proaching the final position shown in 1g'. 2, the bottom ofthe cup- 'b1 will strike the. copper disk p and he ref.. tarded therebyduring. a vrelatively short distance of travel until the bottomof thecup 711 is seated upon the shoulder o1 of block o. When the travel ofthe cup b1 is terminated ,i

y bv the shoulder o1, the force of the projec holder Ic and be unscrewedfrom the top of plug t', after which the holder and sleeveI Z may beremoved andV a new barrel with projectile, etc., substituted.

l'n the initial assembly of the structureVllO 'v ,the plug i may beengaged by a screw driver in the slot i and rotated to assembledposition. As stated before, the disks h and q maintain lthe bore of thebarrel a free from water,

l thereby preventing'l dampening of the eX- plosive charge. -Also theimpact or concussion from the explosion will not transmitted to thewater or to a diver -or other user, this being prevented aty one end ofthe bore of the barrel by the disk lzy and the other 'end bythe cup b1and the projectile -b as viewed in Figa 2'.'

I yThis device' is vcapable 'ofnse' not only where it lis desired toattachrepair or other' 125 plates to the sideof a vessel or the like butalso where it is desired to aliixy lines, -cables,

or ythe like, for various purposes', in which event it is only necessaryto place the end of the barrel against the-side-o the 'body .130

i, into which the projectile is to be driven, as

will be obvious. In this manner laborious and time-consuming drilling,riveting or the like is avoided.

It will also be obvious that there are many other uses to which myinvention may be put, and many modifications and improvements-Which maybe made, so that I do not wish to be restricted to the use or form shownin the accompanying drawings and described in the specification, exceptas defined in the appended claims.
